Obviously this is only in the US, but that's the only market you can buy the Model 3 in at present - and this graphic shows they're outselling each of the premium german marques on the combined sales for multiple models in their class.

I'm not sure many of us (if any, including me!) on here would have though Tesla would have been in this position when we had the Model S to try at our annual meeting way back in 2015...

No, that's estimated sales (i.e. deliveries to customers): refundable deposits are well in excess of 400k for the Model 3 - or were within a week of the reveal 2 years ago, I think they're higher than that now.

Not sure how many of you read New Scientist, but there was an article a couple of weeks ago about the energy requirements for AI which went on to consider cars.
One estimation was that, especially considering the extra sensory equipment, autonomous driving would require about 20% more energy than human-controlled.

And they saw little reason for this to change significantly even if processors etc. became more efficient as the software etc. would just get more complex and functional and soak that up.

In fact they suggested that better AI could encourage more long-distance commuting by car so make things worse!
